چکیده

افزایش تقاضای آب به دلیل رشد جمعیت و کاهش منابع آب متعارف در دسترس به دلیل تغییرات اقلیمی، موجب شده منابع آب غیرمتعارف کشور و به‌طور ویژه منابع آب زیرزمینی ژرف در کانون توجهات قرار گیرند. عدم وجود اطلاعات کافی درباره منابع آب ژرف موجب شد انجام مطالعات شناسایی و اکتشافی این منابع با هدف تبیین وضعیت کشور از نظر وجود آن‌ها در دستور کار دستگاه‌های مختلف حاکمیتی قرار گیرد. در حال حاضر دو مطالعه اصلی مجزا با عناوین "پهنه‌بندی مناطق مستعد آب ژرف کشور" و "اکتشاف منابع آب ژرف سیستان" در این زمینه در حال انجام است که در مطالعات مذکور بیشتر برروی شناسایی موقعیت آبخوان‌های ژرف و حجم آب قابل بهره‌برداری از آن‌ها تمرکز شده است. با‏توجه‏به وجود تجارب جهانی در زمینه بهره‌برداری از منابع آب ژرف، ضرورت دارد سایر جنبه‌های مهم مربوط به این منابع مانند مسائل اجتماعی، زیست‌محیطی، تجدیدپذیری، کیفیت آب و غیره توجه جدی شود. در این مقاله تحقیقات انجام‌شده در سایر مناطق جهان بررسی و ویژگی‌های منابع آب ژرف، محدودیت‌ها و ملاحظات حاکم بر بهره‌برداری از این منابع آبی تشریح شده است.
